Ultrium 960, Ultrium 448, Ultrium 460, Ultrium 230, DLT VS80, SDLT 320 11
1/8 DLT and SDLT Tape Autoloaders
Table 6 DLT VS80 Tape Autoloader specifications
Table 7 SDLT 320 Tape Autoloader specifications
SCSI requirements
The autoloader incorporates a wide SCSI-2 or SCSI-3 (see Table 1 on page 9 for your specific
model) Low-Voltage Differential (LVD) SCSI bus, but may also be attached to a Single-Ended (SE)
SCSI bus. Make sure your SCSI host adapter or controller supports these standards. If you connect
the autoloader to an SE SCSI bus, or if there are SE devices attached to the same SCSI bus, the
autoloader’s performance is limited to the maximum data transfer speed and maximum cable
lengths of the SE bus. For these reasons, HP strongly recommends that you do not use a SE SCSI bus
with the 1/8 Tape Autoloader.
NOTE: Do not connect an Ultrium 960 device to a SE SCSI bus. It will severely degrade
performance.
The 1/8 Tape Autoloader is NOT compatible with a standard differential (Diff) or High-Voltage
Differential (HVD) SCSI bus. The autoloader is compatible with a narrow (50-pin) SCSI bus using a
68-pin to 50-pin adapter that terminates the unused 18 pins (NOT included with the autoloader).
These adapters are sometimes labeled high-byte termination.
NOTE: HP does not recommend connecting any of the Ultrium or SDLT 320 Tape Autoloaders to a
50-pin adapter as this will degrade performance.
